Section 8 Controller Troubleshooting
8.2 Engine Safety Shutdown
Switches
8.2.1
Low Oil Pressure (LOP) Shutdown
If the oil pressure drops while operating the engine, the
normally closed low oil pressure (LOP) switch contacts
close. DC travels to connection 5 on the control panel
and the K2 relay is deenergized.
DC does not travel to the fuel solenoid (FS) or to the fuel
pump (FP) and the engine stops. The red oil pressure
LED on the control panel lights immediately while the
green oil pressure LED cuts off.
Check and correct the generator set fault.
8.2.2
High Water Temperature and High
Exhaust Temperature Shutdown
Switch
If high engine water temperature or exhaust gas
temperature is encountered, the normally open contacts
of the HCHT and HET switch close.
DC travels to
connection 3 or 4 on the control panel deenergizing the
K2 relay.
DC does not travel to the fuel solenoid (FS) or to the fuel
pump (FP) and the engine stops. The red LED of the
high water temperature and/or high exhaust gas
temperature light immediately while the corresponding
green LED cuts off.
Check and correct the generator set fault.
